The Two-Stage Scroll Compressor operates in dual modes: one-stage at 67% for saving mode in moderate environments and two-stage at 100% for power mode in high-demand situations.
The Two-Stage Scroll Compressor is an great solution due to its energy-saving capabilities and ease of installation and repair.
By operating in two stages, the LG Two-Stage Scroll Compressor not only reduces cycling to prevent rapid temperature fluctuations but also enables energy savings through efficient capacity utilization.

What is the advantages of Two-Stage Scroll Compressor?
Firstly, a Two-Stage Scroll Compressor helps to reduce energy loss through flexible capacity. Additionally, The simple structure and weather-resistant external solenoid valve of the Two-Stage Scroll Compressor ensure optimal operation over the lifespan of an HVAC system.
Is a Two-Stage Scroll Compressor better than a Fixed Speed Scroll Compressor?
A Fixed Speed Scroll Compressor operates at full capacity in all operation time. However, Two-Stage Scroll Compressor allows it to operate at full capacity when high-load operation is required or operate in ‘saving mode’ in moderate-load environments. It can provide heightened comfort while reducing overall system energy loss compared to Fixed Speed Scroll Compressor.
How does a Two-Stage Scroll Compressor work?
The Two-Stage Scroll Compressor has a simple mechanism involving an external solenoid valve. When the solenoid valve is off, the compressor operates at a lower capacity. When the solenoid valve is on, it operates at full capacity. This Two-Stage Scroll Compressor maintains a more comfortable temperature when system demand is lower. Additionally, bypass ports optimize the compression ratio in both two modes.
